SEPARATOR AND WASHER.

To all whom it may concern:

Be it known that we, JAMES H. SHAFER and THEODORE CoRNnnLnn, citizens ofthe United States, residing at M adisonville, in the county of Hamiltonand State of Ohio, have invented certain new and useful Improvements inSeparators and lVashers, of which the'following is a specification.

Our invention relates to separators and washers for material such asgravel, coal and the like.

The object of our invention is to provide a device for thoroughlysitting or washing material through a screen with the aid of water,thereby separating the coarse material from the fine and automaticallydischarging the coarse material from one outlet and the fine'materialfrom another outlet.

Another objectof our invention isto provide a machine which may be fedrapidly in large quantities, and which automatically separates andwashes the material deposited therein.

Our invention consists briefly in a receptacle, a. cylindrical screen orwiremesh cylinder suspended therein and submerged partly in water,feeding mechanism communicating with said screen, means whereby saidscreen is rotated, an outlet for the coarse material, and mechanismwhereby the fine material is withdrawn from said receptacle.

Our invention also consists in certain novel parts and combination ofparts and in the details of construction herein set forth and claimed.

in the accompanying drawings which serve to illustrate our invention:Figure 1 is a perspective view. Fig. 2 is a side clevation of same, withparts removed and the casing broken away. Fig. 3 is a rear elevation.

In the embodiment of our invention as illustrated and which shows apreferred construction, 1 represents a receptacle, or tank adapted tohold water,- in which the wire mesh cylindrical screen 2 is suspended.Vertical standards 3 and 4 are provided on each side of the receptacleor tank 1 and are connected at their ends by cross bars 5 and 6 on whichare mounted journals 7 which are adapted to carry a driving shaft- 8.Mounted on the driving shaft 8 are sheaves 9, a-

sprocket 1O thereon at one side of the machine and a bevel gear 11thereon at the other end of said shaft. Horizontal bars 12 are mountedupon the cross bars 5 and G Specification of Letters Patent. Patented J1y 23, 1912, Application filed September 20, 1910. Serial No. 582,840.

and are adapted to carry a shaft'13 at one end thereof which has mountedthereon a beveled .gear 14 which is adapt-ed to mesh" 1' with thebeveled gear 11 on .the driving shaft 8. i

The wire mesh cylindrical sc'reen2 is provided with a frame work 2 orrings 15 which are provided with grooves 16 to receive chains 17 alsothe chains are adapted to pass around sheaves 9zmounted upon thedzivingshaft 8, the cylindrical and end spiders 4 screen 2 beingsuspended upon said chains and rotated thereby when the driving shaft- 8is operated. Mounted atv some suitable place on the framework of thereceptacle 1 and journaled in journals 18 of the shaft 19 are flangedrollers 20 mounted thereon for the purpose of forming a guide andretainer for the cylindrical screen 2, thereby prevent:

ingsaid cylinder from wabbling and jgetting out of position.

A shaft 21 is mounted in the lowe: part i of the receptacle or tank 1 atone end thereof .below the cylindrical screen 2 and isprovided withjournals 22 mounted at some suit able point on the receptacle or tank 1.Mounted upon the shaft 21 are sprockets 23 adapted to receive a sprocketchain 24 having paddles o'r drags 25 thereon. --An operating shaft 26 ismounted at the upper opposite end of the receptacle 1 and is'alsoprovided with sprockets 27 around which the sprocket chain 24 passes.Thisshaft 26 'is also journaled in suitable journals 28 mounted in a.suitable manner upon the reccptacle l. The chain 24 with paddles 25 athereon constitutes an endless conveyer or drag whichremoves/the siftedmaterial from the receptacle-1. At the end of the shaft 26 is mountedasprocket 29 which'is in alinement with the sprocket 10 mounted uponthedriving shaft 8. A sprocket chain 30 connects these two sprockets 10 and29 and thereby forms a means of driving the shafts 26and21.-' i

The operation thus far is readily seen from the illustration in Fig. '1,the driving shaft 8 beingrotated, operates the cylindrical screen,2 alsooperating the sprocket 29', which operates the convever or drags 25 inthe proper direction, the drags forming a means of removing thesand'and' fine "material from the receptacle 1 and pushing it up abovethe board 31 provided at the top of the receptacle 1.

The feeding mechanism is provided on the side of the receptacle 1 andcomprises a hopper or trough 32 having av movable notched floor 33 whichis given a reciprocating motion by mechanism which will now bedescribed. The trough 32 may be mounted as shown upon brackets 3% on thesides of the receptacle 1, and arms'35 extending therefrom to which thesmaller brackets 36 are attached. A dislt or crank wheel 37 is providedon and driven by the shaft 13. A rocker shaft 39 is provided below thefeed trough 32 and is mounted in journals 40 on the sides of thereceptacle 1. A rocker arm 41, is mountedupon said shaft atone endthereof and connects to rod. 38 which is eccentrically connected to thedisk 37, thus imparting an oscillatory motion to the rocker arm all whenthe'disk 37 is operated. Ark other rocker arm 42 is mounted on the shaft39 directly under the central portion of the feed trough 32 and isconnected to the movable bottom 33 of the trough 32 by means of a pitmanas. The rocker arm 42 being fastened tight to the shaft 39 operates thepitman 43, thereby operating the movable bottom 33 of the feed trough 32and imparting a reciprocating motion to the bottom of the trough 32.

The bottom 33 is provided with a groove.

into which the sides of thetrough 32 enter and thereby hold the movablebottom 33 in position during its reciprocating motion.

.l-ollcrs 44 may be'provided and mounted in journals 45 on the arms 35upon which the bottom 33 of the trough 32 may rest, thereby reducing thefriction of the bottom 33 when it is being operated.

The trough 32 is provided with an extension .32 which extends into theside of the receptacle 1 and projects a short distance into the insideof the cylindrical screen 2,

thereby insuring that all the. material put into the trough 32 willeventually deposit into the cylindrical screen 2. An outlet trough orchute 4:6 is provided at the other side of the receptacle 1 and projectsinto the other side of the cylindrical screen 2 through the annularopening in the ring or spider 15.

lllounted on the inside of the wire mesh cylinder 2 and at the endnearest the outlet chute 46 we provide a series of inwardlyextendforming a means of removing said coarse material from thecylindrical screen.

A water supply pipe 4-8 is provided at some suitable portion of themachine which is adapted to supply water to the receptacle l and is alsoadapted to wash the material which has been deposited into the meshcylindrical screen 2. The outlet of the pipe is preferably placed abovethe cylindrical screen 2 and discharges water into said cylinder,thereby washing all fine material through the wire mesh of thecylindrical. screen. 2 down into the receptacle 1 which is adapted to bepractically filled with water. An overflow 49 is provided in thereceptacle 1 near the top, thereby keeping the water in the receptacle 1at a constant level.

The portion of the receptacle 1. which lies underneath the drag chains24 is filled with line sand in order to provide a soft bed for the drags25 to operate upon.- The sand or fine material is constantly fallingthrough the wire mesh screen of the cylindrical screen 2 and settling inthe bottom of the receptacle 1, and is being dragged out by means of thedrags or paddles 25 upon the incline surface of the embankment of sand50, as best shown in Fig. 2.

The operation of the device is as follows: The rough material such assand or coal is dumped into the feeding trough 32 and is thereby fed bymeans of the reciprocating movable floor in said trough gradually intothe cylindrical screen 2, which being rotated gradually sifts the sand,with 'the help of the water supply constantly flowing into thereceptacle 1, through the mesh cylindrical screen 2. The coarsermaterial remains in the cylindrical screen 2 and gradually works to theother end. thereof Where it enters the pockets between the extendingfianges'of wire mesh 47 and is carried by said extensions up to thechute 46 at the upper end of the cylindrical screen 2 and is thereby deposited into the chute and carried by gravity to the outside of saidreceptacle. "While this is being done, the dragging device is constantly dragging the sand from the receptacle 1, thereby forcing it outover the edge of the receptacle 1, the drags 25 being driven in thedirection of the arrow shown in. Fig.

lhe bed of sand 50 is provided in. order to allow the paddles 25 to havea surface and yieldab'le bed to drag over so that a stone hard particlewhich might have strayed into the bed will not destroy the paddle whichit engages.

This device is a positive separator which completely separates the sandfrom the coarse material, and by varying the mesh from the smaller orinlet end l the cylin der to the larger end, the sand may be graded fromvery fine sand to very coarse sand.

The device is adapted not only for sepa- 1 be made Without departingfrom its spirit and scope, and We do not Wish to be confined llO'll'lBexact details shown.
